Austin appears at No 21 on the list.

“Live music is the essence of Austin, but it isn’t even close to the whole story. With spectacular entertainment districts, ubiquitous culture, and top-notch restaurants, Austin allows you to create your own soundtrack,” Tripadvisor says. “Austin boasts more than 250 music venues, the world’s first James Beard Award-winning [barbecue] pitmaster, an eclectic arts scene, and the unique migration of 1.5 million Mexican free-tailed bats. Take a look around and put the Live Music Capital of the World on your playlist.”

“Step to the beat of wafting flamenco music as you wander the downtown River Walk before sampling as much chili (San Antonio’s signature dish) as your taste buds will allow,” Tripadvisor says. “A visit to the Alamo is an absolute must, as is taking in a show at the ornate Majestic Theatre. San Antonio Missions National Historical Park is dotted with 18th-century buildings and features, making for an enriching excursion.”

It's no surprise that San Antonio made the list. In addition to hosting about 37 million visitors a year — which contributes $15.2 billion to the local economy — its world-class attractions, luxe accommodations, and even H-E-B tortillas have made it a must-hit destination for travelers across the globe.

Elsewhere across the state, Houston grabs the No. 13 spot on Tripadvisor’s list of the top 25 trending destinations in the U.S., the only Texas city. Trending destinations were determined using an algorithm that measured year-over-year increases in positive Tripadvisor ratings for accommodations, restaurants, and attractions, and measured increases in booking interest and searches.

“Houston hums with an energy and independent spirit all its own. A leading cultural and culinary destination in the South, the city is home to over 11,000 restaurants featuring cuisine from more than 70 countries,” Tripadvisor says. “The thriving arts scene includes resident opera, ballet, symphony and theater companies. The Museum District houses 19 museums, all within walking distance. Be sure to visit Space Center Houston, where you can visit NASA’s Historic Mission Control at the Johnson Space Center.”
